UIM Probe administration - IP write mask defaults

I have noticed in probe administration that there an individual IP address for some probes and IP mask for others.Are these put in place by default when the application is installed?If they are not what is the default for the IP mask when the application is installed?

Environment:

UIM 9.0 and earlierHUB 7.95 and earlier

Answer:

When the UIM application is installed we do not know about the IP schema it will be installed to.By default all IP mask for probe administration start out as wild card of an *.If any individual IP or IP mask is set then this has been changed by and local administrator.
